To solve the brake thermal recession of traditional brake, an integrated brake of double-disc frictional and electromagnetic was proposed. For a certain car, the integrated brake of double-disc frictional with electromagnetic was designed. Through simulation and bench test, torque characteristic of the integrated brake was studied. Results showed that the theoretical designing curve agreed well with the experimental curve. The electromagnetic brake device of the integrated brake can provide a braking torque for 180-202N.m, thus it can effectively improve the brake thermal recession.
